My` invention "relates to sash-holders, and consists in the construction and fnovel arrangement of a spring ononefside of the sash, incombination with an ar-I "rangement `ofrollers on the otherv side, whereby the sash becomes fixed `at anylheight to which'it may be g raised. y

side of the sash, and should haveseveral bearings.

`Sncha spring is shown at iig. 2. It is secured to the sash by a screw at one end', the other end being. free to extend itself longitudinally.

This spring is formed in the shape of a W, andjhas a bearing, z, at each end.

`The free end of the sp1-ing is slotted, to allow of extension in the direction of its length.

. This endof the spring is vconfined to the sash by means of the pin n, passedA through the slot s.

Inmoving the sash it should be compressed toward the spring side. This will give the pulley freedom of action, and decrease the friction suiciently to allow the sash to move easily'.

Instead of a single roller, several may be used on one side of the sash. Where a' single springl is opposed 'it is advantageous to employ two rollers, one at each end of theisash. 4WhatV I claim as my invention, and desire to `,se-

The `W-shaped spring d, attached to the window# y sash rmly at one end, and slotted at s to receive the .pin n, and forced against the sash by thefrollers on the opposite side,.snbstantially as specified.

In testimony that I claim the above I have hereunto subscribed my name in the presence of two wit- Witnes'ses: JOSEPH W. MEGAW.
